I met a nursing student in Shanghai who ended up marrying a "driver". (For reference, the way you get into nursing school in China is by flunking the college entrance exam.)
Attending Fudan University, I also met several students there and at the school across the street, Shanghai University of Finance and Economics. Both are highly prestigious.
Everyone's graduated by now, and the most materially successful of all the contacts I made, by far, is the nurse. She already owns a Tesla and an apartment in Shanghai. (She also has a child, which is true of only one of the university students.) What's her secret?
The couple's parents bought those things for them.
Quick question: what is the only country mentioned in my comment above?
Was that all an illusion? If so, what image were you trying to present? Why?
So, if it turns out your friend isn't a nurse, doesn't have a high salary, and doesn't live in San Francisco, or some combination thereof, I'm going to score that as a giant lapse in reading comprehension in a thread about high salaries in San Francisco.
